From: Jitao Shi <jitao.shi@xxxxxxxxxxxx> Old sequence: 1. Pull the MIPI signal high 2. Delay & Dsi_reset 3. Set the dsi timing register 4. dsi clk & lanes leave ulp mode and enter hs mode New sequence: 1. Set the dsi timing register 2. Pull the MIPI signal high 3. Delay & Dsi_reset 4. dsi clk & lanes leave ulp mode and enter hs mode In the new sequence 2 & 3 & 4 will be moved to dsi_enbale in later patch.
